Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a wound measuring ruler. Background Art

[0002] In clinical practice, it is often necessary to measure the size of a patient's wound in order to evaluate the progress of wound healing. Medical staff usually use the maximum length and width method to measure wounds, that is, use a medical wound measuring ruler to measure the maximum length and maximum width of the wound from edge to edge, and multiply the length and width to get the estimated area of ​​the wound. Regularly evaluating changes in wound area can help predict whether the wound can heal within a reasonable time.

[0003] Most existing wound measurement tools are disposable folding rulers with scales, which can only measure the length and width of the patient's wound, while the wound depth is measured by inserting a cotton swab into the deepest part of the wound, resulting in low work efficiency of medical staff. In addition, in addition to the indicators of the length, width and depth of the wound, the depth azimuth of the wound is also an important indicator for case analysis. At present, the measurement and description of the depth azimuth relies on the experience and subjective judgment of medical staff, and there is a problem of inaccurate data. Utility Model Content

[0008] After the measurement is completed, the depth measuring part is rotated to make it parallel to the angle measuring part, the width measuring ruler and the length measuring ruler are folded, and the angle and front and back position of the angle measuring part are adjusted to make it shrink on the surface of the measuring ruler body.

[0011] The cross section of the rotating shaft is an "I"-shaped structure, a scale is provided on the upper end surface of the rotating shaft, and the middle part of the rotating shaft is a connecting shaft.

[0012] The rotating rod and the rotating disk are sleeved on the connecting shaft in sequence, and the limiting hook claw cooperates with the limiting groove; the diameter of the upper surface of the rotating disk is larger than the diameter of the upper end surface of the rotating shaft; when the rotating shaft rotates, the rotating disk rotates accordingly, and the value on the scale is read through the pointer on it.

[0014] Furthermore, the disposable sanitary device is a silicone sleeve with scales.

[0015] When not in use, the wound measuring ruler is folded as a whole. When in use, first unfold the length measuring ruler and the width measuring ruler, then rotate the angle measuring part to align the pointer with the initial position of the scale; secondly, rotate the depth detection rod to make it perpendicular to the rotating rod; then, adjust the front and rear position of the rotating rod so that the depth detection rod is located directly above the wound detection point, and then you can start wound measurement. When measuring, you can operate the rotating operating button to drive the depth detection rod to move downward to the bottom of the wound to detect the depth of the wound.

[0016] After the measurement is completed, record the length, width, depth and angle of the wound, then discard the disposable sanitary device and fold the wound measuring ruler.
